CENTRIFUGAL WINNOWING APPARATUS.

SPECIFICATION forming part of Letters PatentNo. 455,977, dated July 14,1891.

Application filed April 4, 1890. Serial No. 346,519. (No model.)

To @ZZ whom, z5 may concern.:

Be it known that I, OLOF SUNDGREN, a subject of the King of Sweden,residing at Osterand outward into the air by means of a rodrum.

tating disk or drum. This apparatus differs from others employed for thesame purpose partly in the devices for conducting the particles into onedisk and partly in other details, whereby the particles, instead ofbeing thrown straight outward in a horizontal direction, are

thrown outward and upward atan angle of about. thirty degrees with thehorizon. Further, the particles are not thrown out around ,the wholecircumference of the disk, but only around a part of the sametoward oneor more sides of the apparatus.

In the accompanying drawings, Figurel represents, partly in sideelevation' and partly in vertical section, apparatus embodying myinvention; Fig. 2, another side elevation, partly in section, of thesame apparatus; and Fig. 3 represents a plan of same. Fig. 4 represents,partly in elevation and partly in Vertical section, one form of thethrowing-disk and other details, hereinafter more fully described. Fig.5 represents in vert-ical section a modified form of the throwing disk,bowl, wheel, or Fig. C represents a plan view of one form of thethrowing disk, bowl, wheel, or drum. Fig. 7 represents in plan andvertical Section another modified form of the throwing wheel, bowl, ordisk; and Fig. 8 represents, also in plan and vertical section, anothermodified form of same. Fig. 9 illustrates certain adjustable doors,hereinafter more fully described.

wheel, to be thrown by the centrifugal force outward and upward towardthe circumference, under the lid C, and out of the disk or wheel, inorder that the matter may immediately acquire the rot-ary motion of thedisk, and thereby get under the influence of the centrifugal force andbe thrown ou t. are wings or partitions E extending almost radially andcatching the matter. These wings serve likewise to hold the lid C. Thematter is fed into the throwingedisk by means of the funnel .or hopperF, at the lower end of which is a feeding-roller G. In connection withthe funnel is sometimes used the iuclined plane H, (see Fig. 1,) theytop of which constitutes a sieve. the inclined plane ll and drops theninto the funnel. The m a'tterpassing through the sieve in the inclinedplane H is conducted down to the throwing-disk by means of a funnel T,located under the sieve, and enters thusinto the disk at another placenearer the circumference of the disk or drum B than. does the matterdropping down through the funnel F, and consequently the coarser andiiner matter escapes at different parts of the circumference of thedisk. y The sieve or planeI H, with its funnel T, is indicated by dottedlines only in the drawings, as it is only intended for matter consistingof pieces or particles of very different sizes..

To the feeding-roller G motion is transmitted from the shaft A by meansof the interm ediate sliaftA,wl1eels, and belts or cords, as clearlyrepresented in the drawings.

The wings in the throwing-disk, the bottom of which, as represented inFigs. l, 2, and 4, has an inclination of about thirty degrees, are notdisposed radially, but the outer' parts lie in directions or linestangential to a circle concentric with the disk but of muchA lessdiameter, in order that the matter may leave the disk sooner than itwould if the wings had Aa radial position throughout their whole length.

For collecting the matter there are suitable collecting-compartmentslocated at the side of the apparatus. These compartments need not extendall around the apparatus, but only that part of it obliquely in front`of thefunnel or funnels, the exact position depending upon how far theparticles are driven around by the rotation of the disk. The matter isrIlhere The matter passes first i IOO thrown out at one or two sides ofthe appa l'atus, according to Whether the feeding takes place at one orat two places. At trials made it has been proven that the matter isthrown along about a quarter of the circumference of the disk in advanceof the position of the funnel.

In Fig. 4 two feeding-funnels F are represented.

In the modification represented in Fig. 5 thethrowing-disk is providedwith a number of lids or bottoms C, the parts of which situated next tothe center being horizontal sieves, while the outer portions havegreater inclinations relatively to each other in proportion to theirheight aboveV the bottom. The sieves are finer relatively to each other,according to their height above the bottom, the lowest being the finest,so that the finest altgter falls to the bottom of the throwing- 1s Othermodifications of the throwing disk are easy to devise-such, for example,as are represented in Figs. 7, 8, and 9. By these figures it ,will beseen that the disk itself may be bowl-shaped and the wings curved, sothat thelattermaybealternatelylongerand shorter from the circumferencetoward the center of the disk. (See E and E, Fig. 7.) Small additionalwings E may be employed, if desired, to change and adjust the directionof the discharge orto cause the matter to follow the inner sides of thewings. L indicates the openings through which the material is thrown outof the disk. j

In order to adjust the throwing angle more exactly, some adjustabledoors K may be adapted at the outer ends of the wings, as represented inFigs. 8 and 9. The door K is pivoted to one or more shafts or bolts`proj ecting outward from the end of a wing or from the disk, so that itmay be adjusted in different inclinations. Thematter is hit by thesedoors when leaving the disk, and receives thus an impulse by which itsdirection of motion is modified, according to the position of the doors.IJastly, it should be remarked that the lid C likewise may be inclinedmore or less upward.

Having thus described my invention, what I claim as new, and desire tosecure bv Letters Patent, is-

l. In a separator, the combiiiation, with the feed-roller, operatingmeans therefor, and a revolving disk, of an inclined plane, the upperpart of which constitutes a sieve, a funnel for conducting matter fromthe sieve to the feeding-roller, and another funnel located in front ofthe lower end of the plane conducting matter from the sieve to thethrowing-disk direct, the said funnels feeding the material to the diskbetween the center and the periphery thereof, substantially asspecified.

2. In a separator, the combination, with a shaft and operating means forthe same, of a rotating disk provided with a plurality of lids locatedone above the otherand having different angles of inclination, thetopmost lid having an opening at the center and the others provided withsieves, said sieves being finer in proportion as they are locatedfarther down, substantially as specified.

3. In a separator, the combination, wit-l1 a shaft and operating meansfor the same, of a rotating disk provided with a plurality of lidslocated one above the other and having different angles of inclination,the topmost lid having an opening at the center and the others providedwith sieves,'said sieves being finer in proportion as they are locatedfarther down, and substantially radial wings between said lids', as andfor the purpose specified.

In witness whereof I have hereunto signed my name in the presence of twoSubscribing witnesses.
